Appiimion nled october a1, 191s. serial Nusa-12o.

This invention relates to ycomputin machines of the kind in'which the numera keys set up indexing devices, which subsequently control the extent to which the number wheels or.' parts of a register or totalizer are turnedby a general operator. l

One of the principal objects of the invention is to provide improved means for effecting the operation of a plurality of registers.

Any suitable registering mechanism may be taken as a basis for a single register; and

one -or more additional registers may be operatively connected to the first register to be driven simultaneously therewith; whereby a single set of indexing devices may serve to control the extentof operation of several registers or totalizers. y

This invention is preferablyl applied to machines in which a typewriting mechanism is combined with a computing mechanism. The carriage of the typewriter is usually employed for selecting the denominations, while the keys select the digits of the indexing mechanism; and a single setting of the indexv devices answers fortwo or more registers.

The wheels usually` comprising a register in an Underwood-Hanson machine are usually driven by means of bars which are advanced by means of a general operator; said bars having racks to engage pinions on the number wheels. Said bars also vcarry index pins, and are also arranged to be vdisplaced one by one-by means of connections on the typewriter carriageat the index-setting operation..

The additional register or registers are provided with dead driving. bars, that is, these additional drivingbar's do not any indexing devices, and are connected by y means of cross connections to the wheel driving bars of the usual reglster, which 1s here- 1n termed for convenlence, the mam or major register.

l Each of the main register driving bars has an additlonal rack, which is connected by a tram of gear-in with the corresponding'bar on each of t 'e other registers; said train of gearing referably comprising two pmions' and a s aft on which they are mounted; one pinion meshing with the rack on themaln drlving bar, and the other meshing with the corresponding rack 'on the driven bar.

Each register is provided with a shiftable device. so that it may be either adding- 4or subtractlng or silenced, while each of the remaining registers is either adding, subtracting or silenced. These lshii'table de- -vices are placed under the control of the typewriter carriage, Vso that whether the registers shall add, subtract or be neutral at the operation of the general operator, depends upon the position of the typewriter carriage, or in other words, depends upon the position of the column on the work-sheet in' which the computation is being performed. Upon the carriage is placed va dog forv selecting the digits of the indexing mechanism; and connected to this dog v are devices to determine the operation ofthe aforesaid 'shiftable devices, which in turn control the computations ofthe several registers. .A

Each of said shifta'ble devices may be operated by a bar, and a spring norm-ally tends to operate said bar. The bar is restrained by a latch, and the device which is adjustable along the carriage is adapted to withdraw said latch; said bar being afterward returned to normal position by the general operator against the tension of said spring,

Each latch vis connected to a cam, which may be engaged by an adjustable tappet on the carriage; and preferably these cams are placed one behindanother, so that the same tappet may controll all of the cams, that is, may withdraw all of the latches simultaneously. Several of these combined ,digitvselecting dogs and cam-controlling tappets may be adjustedto different points along a rack on` the carriage, to correspond tothe positions which the several columns are to occupy on the work-sheet. Moreover, the tappets may be of vari-ous forms; for insta-nce, the -first tappet may be arran4 ed to cause the first register to be set toad ition, y

' and the second and third tol subtraction;

register as the first column is written, while the remaining registers are silenced. The second tappet may be arranged for the performance of addition on the second reglster as the second column is written, while the first re ister and the remaining registers are also si enced. So likewise at the third eolumn addition `may be performed .on the third register, while all the remalmn registers are silenced, and so on; so that t e various registers may be ysingly operated iny succession as thel numbers are written in consecutive columns. These are only a few. of the very wide range of eombinatlons that may be emplo ed. referably there'ls also al provision vor manually controlling the condition of the registers.

The adjustable member 'which'carrles the digit-selectmg dog and the condition-controlling tappets, may also serve as a column stop, to coperate with the usual decimal or 'other counter-stops on the'framework of the machine, so that, by selecting the proper tapet gn the carriage rack, and thereby determine the locationof the column on the work-sheet,

' and also determine what the various registers shall do when the numbers written in said column are run into the .registers, a .nd l also 'set the digit-selecting dog into p osltlon to'coperate in the proper manner wlth the' index-pin setting devices. I Other objects and advantages w1ll hereinafter appear.

Numeral keys 1 and alphabet keys 2 oper- .ate levers 3, '4, to vibrate type-bars 5 upwardly, to strike against-the front side of a platen 6 mounted on a carriage 7 which travels on a rail 8, and is cntrolled by a rack 9 meshing with a pinion 10 connected to an escapement wheel 11.

Each type-bar has-a heel-'12v to engage a .universal bar 13 mounted on a frame 14 tending horizontal rock shafts20, formin parts of linkages which depress the index pll'lS. l 4 5 Each rock shaft carries -an `upstanding arm 21 to engage a wrist or pin 22 upon a horizontal link 23, which extends from side to side of the machine.

At its ends, each link connects a pair of bell cranks 24, the long arms 25 of which are connected by links 26 which descend to press down index pins 27. Each numeral key thus determines the value of the index pin which is depressed or selected, `but the typewriter carriage 7 determines the denomination of the depressed pin; each link l or depressor'bar26 being capable of depressing one pin in eachdenominatiom The index pins are arranged in rows upon bars 28, extending forwardly 'and .rearwardly beneath the links 26, and serving eventually to rotate the number wheels in a manner presently yto be described.

Normally the index pins are out of the path of movement of the depressor bars 26,

tappets', marked to indibut as `the 'paper carriage 7 feeds step-bystep, the bars 28 are displaced forwardly one after another, to positions to bringl their p ins within; range of the depressor bars 26 (see Fig. 8), sothat any bar 26'may depress the corresponding in of the forwardly displaced pin-bar. I eans for'displacing the pin bars forwardly one after another during the movement of the paper carriage, will presently be referred t0. v i' Such index pins as are depressed, project below the bars 2 8 on which they are carried, and serve as lugs whereby said bars may be driven endwise forwar y for turning the ynumberl wheels. Theyare driven by means of a universal driver in the form of a trans-V Versel horizontal bar 29 which forms part of for every calculation. l

The general operator in a general operator which isoperated onceV the Underwood- .Hanson combined-l adding and typewriting machine com rises side bars 30 (Fig. 4)

which are sli `in guides on the side walls of the framework and are rigidly united to form, a slideor carriage; said cross bar 29 forming one ofthe devices for tying said bars 30 together.l This carriage or general operator may' be driven .by a crank 31 which is fixed upon a `transverse horizontal rock shaft 32 journaled at its ends in the framework of the machine, and carrying at its ends segments 33 'which meshwith idle pinions 34, the latter meshing with racks 35 v formed. upon said general operator side bars30.

A movement vof the crank 31 forwardly from the Fig. 3 .position causes the general operator to drive forwardly, and the bar 29 thereon engages any depressed index pins 27, 4and drives forwardly the barsl 28 on vwhich they are mounted.

At its forward end each of said index pin v bars 28 carries an addition rack 36 norp mally out'of mesh with a pinion 37, which is ixedto a number wheel 38 forming one of a gang, there being one pin bar 28 for each number wheel in'said gang. These number wheels are arranged" below a sight opening 39 in the casing of the machine. Thecross bar 29, which engages the depressed index pins, isplaced some distance' behind said pins, so as to permit considerable lost motion of 'the general operator before the first pin can'be engaged by said cross bar, and duringthis lost motion, the racks 36 become meshed with .the number 4 wheel pinions 37. This result is effected in the following manner; Carried upon power shaft 32 and rotated thereby is a disk 440 having a cam 67, which, as soon as the crank 31 starts to turn, engages arider or awl 41 pivoted at 42 upon an arm 43 of a ever 45, which is fixed to and turns upon a transverse' horizontal rock-shaft 44 and swings said lever from the normal position seen at Fig. 3 tothe position seenat Fig. 7 so that to drive forward under the impulse of the crank 31, the pinions are turned clockwise at y Fig. 7 and the number wheels are turned in the same forward direction, thus performing addition; each number wheel bemg advanced to an extent dependent pcpon whlch of its index pins 27 was depress After the crank 31 has 4been given a full forward stroke, it is swung backwardly to normal position to restore the general operator to its normal position. t the initial portion of the return stroke of the crank 31 and its shaft 32, the rider or pawl 41 turns counter-clockwise at Fig. 7 (the cam 40 now turning in the reverse direction from that 36, but above the pinion 37; and is con-l nectedfby an arm 60 with the forward end of the bar 28.

To cause the wheels 38 to subtract at the driving strokes of the index bars 28, it is only necessary to move the computation pinions 37 into mesh with thesubtraction racks 59, instead of the addition racks 36, so that the number wheels will .be turned backwardly at the ensuing forward drive of the index bars 28. v

To determine whether the register shall p add, subtract, or remain silenced at the operindicated by the arrow at said figure), and

by a ve slight rotation of said pivot 42 said paw is rendered no longer capable o supporting the arm 43. This permits springs 47 to draw rearwardly C-sha ed or double cam levers or arms 47 pivote at 47", which engage the ends of said arbor 49 and thereby raise said wheels clear of the rack bars 36, so that the arts 43 and 45 are restored to their norma positions. v

This movement, which withdraws the pinions 37 from the addition racks 36, takes place before the racks themselves start upon their return or rearward movement to nor mal position; such return being preferably eected by the same cross bar 29 which reviousl carried the racks forward. e' cross ar, for this purpose, engages lugs 48 pendent from the rack bars in the rear of the cross bar 29,but is arranged to have considerable idle rearward motion (enough to permit collapse of pawl 41) before engaging entl said lugs 48.

The arbor 49 on which the number wheels 38 and their pinions 37 are mounted, `forms a tie-rod connecting the two sides 50 and 51 a second disk 64;v havin ation of the general operator, there is employed a condition-controlling bar 62, (having an operating spring 62). This bar extends from front to rear of the machine, and slides on a rest 62. Betweenits ends, this displacing the latter and silencingthe pawl 41. At .the `same time is brought into play4 a cam 68, also fast to'said sleeve, lwhich isk is effective only fory vthe purpose of subtraction. Thus said,

bar 62 operates t shift the register-actuatinmechanism from addition to subtraction.

his dis'k64 is arranged to coperate with av follower or pawl 65, which is out ofuline with-the pawl 41,-that is, it works in a dif.-

ferent plane; the disk 64 being shifted into of a swinging frame, which has'bearings orv sockets at 52 to swing upon collars 53 carried by a transverse horizontal shaft 54; this shaft forming a convenient hinged support for said frame 50, 51, and keeping the computing wheels always in proper relationship to the'shaft 54,.w ich is connected to the general operator and carries certain prime' movin tens-carrying devices, aswill prese explained. Q

'T e side members 50, 51 are also connected by a tie-rod 55. The arm 4 5n ofthe shifting lever ma be duplicated at 56, andthe link 46 may e duplicated at 57; the shaftl 44 forming a rigid connection between 45* and 56, so that the linksj46, 57 ull down both s1des of thev number whee shifting the same plane as its pawl 65 when the vcam disk' 40 is shifted out of engagement with the pawl 41. Y v

During the ensuing forward stroke of the eneral operator, the cam disk 40 will rotate idly; but the cam disk 64, as seen at Fig. 3, will engage the follower or awl 65, and thrust down the arm 74 of the ever 45 from normal midway position to the depressed position as seen at Fig. 12, thus drawing upwardly the links ,46 and 57 thereby lifting the frame 50, 51, 88, and carrying the pinion 37 into mesh with the subtraction racks 59, so that the latter are enabled'to turn the number wheels backwardly during the remainder of the forward stroke of the general opera'- tor. `On the return stroke, the pawl 65 re, leases the arm 74, and thenthe cam arms 47 draw the pinions 37 clear of the racks 59.

The means for controlling the position of the shiftable condition-controlling bars 62,

will presently be explained.

The pawls 41 and 65 are provided with 90 rod carries a general cam 63, which during general operator, to connect said operator :,mpoji springs 66 which restore the pawls to norma-l positions at the end of the return stroke of' the eneral o rator. Normall springs 47 and garms 47,p`i 3, 10, holdthe lever 45 in its midway position, and the pawls 41 and stand ready. for engagement with their respective cams 67 and 68, as at, Fig. 3.

These cam disks 40, 64 are splined to the shaft 32v by means of a pin 69 carried on an armV 70 fixed to said shaft, and passing through 'a hole in disk l40. v

The carry-over devices comprlse'an idle pinion 71, meshing with a rack 72 on the with a pinion 73 on the horizontal transverse` shaft 54 having a helical series of cams or tappets 75 for carrying tens at the addition o ration. This shaft 54 ,turns in onlyl one dlrection, Iand is operated only during the return stroke of the general operator; being for thisv pur ose connected by a ball clutch mechanism 6 to the pinion 73,.

as seen in Fig. 2. A spring 131'* holds adetent 132", Fig. 4, to prevent backward rota- .tion of the shaft 54.

Each number wheel (except that of low'- est denomination) has an individual train of mechanism for connecting it to this power-driven tens-carrying shaft 54, but the train is normally broken, 4and hence the tap-- pets or cams 75 are all normally ineHective.

Each number wheel 38 (except that of hi hest denomination) `has a starting tooth 7, the function of which is to establish a connection from the vnumber wheel 'of next higher denomination to the tens-carrying shaft 54. A

lEach of the trains of connecting devices includes a pawl 78 to mesh with a gear 79 fixed upon the number wheel,.the pawl having multiple teeth 80, or being in the form of a short rack, as shown. Each rack is rior-'- mally out of mesh with its gear wheel 79, but the general operator o crates means to shift its pawl up into mes with its -pinion, and the starting tooth 77 o crates means to provide for the subsequent riving movement ofthe pawl.

To this end, the pawl 78'has a pin-andslot connection atv .81 with al two-armed lever or tumbler between the power-driven tens-carrying cams-7 5 and the number wheel rotating pawl 78; this lever being' pivoted between its ends upon an arbor 82, and having a short arm 83 providedY with a pin` 84 in the path of said starting .or setting tooth 77.

The number wheel 38 turns in .the direction of the arrow, or clockwise, as at Fig. 7,

to perform addition. The setting tooth 77%.

at the completion of a full revolution o said number wheel 38, engages and depresses the pin 84 together with the arm 83, swinging said lever, rocker or interponent.

The lower arm 85 of said lever -or rocker Va rod 88 which rigidly connects arms 89 has a slot to engage with the in 81 on the tens-carrying pawl 78, which y the movement of the rocker, is drawn back from the normal position at Fig. 7. Upon said arm 85 is a cam-like tooth 86, which is swung into the path of the associated tappet 75 on the tens-carrying shaft 54, the function of the latter belng to act upon said tooth 86, and thereby return the rocker forward to its normal position. During such return movement, the rocker arm 85 carries with it the pawl 78, which, however, has in the meantime been swung up into mesh with the gear-79 of the number wheel next higher than that which carries the setting tooth 77, whose movement has just been mentioned.

The forward swing of the pawl 78 is' effe'cted by the engagement of the tappet 75 wlth the rocker tooth 86, there being provided upon the tens-carrylng shaft 54 a cam pawl 78 and lifts the forward end thereof into mesh with said gear 79 as at Fig. 11; the

pawl being supported between its ends by 90 endent from the side plates 50, 51, thus ormmg part of the frame which comprises the arbor 49 vand which extends forwardly from the collars 53. on said'shaft 54, to rock up and down for shifting the adding pinions ilnto and out of mesh with the driving racks 36. l

By means of said pawl 78, the higher number wheel is advanced one point. The cam 87 has a continuation or dwell portion 100 90 which holds down the rear end 96 of the pawl 78 during the wheel driving movement, and which thereupon releases said pawl and permits the forward end thereof to be'snapped down by'a spring 91 out of' mesh 105.-

'with the gear 7 9 a spring detent 92 engaging. the latter to hold the number wheel in posltlon.

l At the subtracting operation, which in cludes what may be called tens-borrowing, l

th'e setting tooth 77 .on the number wheel,

which is traveling counter-clockwise (Fig. 12), lifts the arm 83 and swings the rocker to the Fig. 12 position. h

The upper arm 93 of the rocker has a 115 tooth 94 which is swung into the path of a cam or tappet 95 on the power'shaft 54; the tappets 95 being spirally arranged and vbeing paired with the tappets 75. The tappets 95 are in different planes from the tap- 120.

pets 75, and the tooth 94 is correspondin ly offset .from thefarm 93. The cam 87 (glepresses the rear arm 96 of the pawl 78 and elevates the front arml thereof into mesh with the gear 79, and then the tappet 95 cam- 125 mingor acting upon the tooth 94, swings the rocker 93, 85 Ato the normal midway lposition atFlg. 1l; thus drawing backwardly the pawl 78. At the conclusion of the tensborrowing operation, the can; 87 releases the 130 v rear arm 96 of the pawl, and the forward arm of the latterv is drawn down by the spring 91 as before.A

Each cam. 87, together with its -assoclated tappets 75 and 95, forms a group, and sald groups, as seen at Fig. 1 5, are arranged spirally on the shaft 54, so -that the computing wheels are successively voperated'by the carry-over devices,

from lower to higher denominations. v

The rockeror tumbler 85, 93, isheld 1n any of its three positions by' means. of a catch 97 pivoted upon a rod 98, which rod\ connects the side plates 50, 51, just in fronty of the rod 55, and said catchl 1s pressed.

downwardly by a spring 99 coiled around .the rod 55; the catch A having three notches the usual manner, and is pivoted as usual 100', 101 and 102 to engage a pin 103 on the tumbler to holdl the same in any of three positions. y y' All of the'tens-carrying trains aremounted upon theswinging frame 50,51, and the' number of wheels *with their pinions, de-

- tents 92, gears and vtens-carrying trains,

swing up and down -as a unit aboutv said power shaft 54, which serves as ka support for the rear end'of said frame, as already' explained. The 'raising of the universal plate 108 'restores the index pins 27l to nor-v mal positions. Theplate 108 is operated in 28 forwardly so as to-bring the in ex pins 27 into register with the pin-de ressing link- -ages 26, may be of any suita le construcv tion, and may comprlse vertical levers 124 pivoted'between their ends at 125, the lower ends of these levers being adapted to strike' the rearends of the index pin bars 28'.' At' their upper ends, these levers are engageable by bevel dogsv 126 pivoted upon lugs 127 on the carriage 7 the levers being arranged at letter-space intervals, so that at each letterfeeding movement of the carriage 7, one of the levers 124 is vibrated,and the index pin bar 28 of corresponding denomination is set forwardly, so as to bring its pins within range of the depressors`26.

The levers 124 are so formed that the de-'- nominational o rder or their upper ends is the inverse of their lower ends. The dogs i 126 are individually pivoted vso as to permit them toride idly over the ends of the levers 124 while the carriage is beingv returned.

pinion 136 meshing with a rack- 137 -videdupon the bar 28, and a pinion 138 meshing with a similar rack 139, Figs. 6, 7

Returning springs 128 are provided for the levers 124, and pivoted fingers 129 are pressed by springs 130 against shoulders 131' on the index pin bars. 28, to return them *one after another. from the positions to which they are'displaced bythe levers 124, said fingers 129 ridlng idly on the top edges ofsaid index pin'bars 28 during the wheel driving movements of the latter.v

At Fig. 4 is seen a second adding head, t0- talizer or register 133, comprisin a gang of number wheels 134, construct and connected like the wheels 38 in the main totalizer (which is designated'generally as 132). It will be understood that all the description as heretofore applied to the register :132, inclusive of thev tens-carrying mechanism, applies also to the register 133; and Figs..1, 10 and .11 are drawings of the register 133 as well vas of the-register 132. The

register 133 itself is' seen in sectional side elevation atFig. 7; this register being at the left side of the machine.

The single indexing mechanism already described, and includmg the single set ofv index pins 27, answers for both registers 132 land133. 4The number wheels 134 are -connected to the rack bars 28 to be driven thereby. Connection is effected by means of a series of cross `shafts 135, one for each number wheel. 'Each shaft has a driving proand `9, on'bars 140, which correspond with the-bars :28, and have .at their forward ends racks 141. and 142 to correspond 'with the racks 36 and 59 on the bars 28, whereby the equipped pinions 37 of the number wheels 134 areactuated, the same as in the register 132.

The bars 140 are not provided with index pins 27,- norv lwith' carriage-controlled denominationfselecting devices. The crossshafts 135 are denominational, the units rack bar 28 beingv connected' by its own cross-shaft' with the units bar 140, the tens bar 28 with the tens bar 140, and so on. The` cross-shafts 135 may be placed in a row, or one behind another, Fi .5,-to bring the shaft .driving racks 1 37 ont e same level, Fig. 3. The bars .-140 arev guided in' forward guidecombs and 140, and a rear guide comb Whenever any number isrun up on the maJor register 132, the same nu'mber may be run up on the sub-register 133 hence the Iatter may be'employed for sub-totals, as for instance, itmay givethe total of the items on each of a series of bills, while the major totalizer 132 will give the gross sum of the items on'all the bills.

Where three or more registers are required, the cross shafts 135 are extended to the additional register or registers, and provided'` with suitable f-pinions to drivelthe carriage 7 and ,t

by the numeral keys of the typewriter. The

slngle denominatlonselecting mechanism 124, 126, etc., serves for all three registers, and whenever an number is carried into 'the re 'ster 132, 1t may be simultaneously carrie into the registers 133 and 143.

Cam 63 on each of the subtraction shift Ibars 62, 149 and 153 is provided with a neutralizi surface or portion 151, to hold the shi table member 63s lin a position mid' way of the extreme positions to which it may be shifted along the'main operating shaft 32, so that both of the cam disks 40 and 64 will be out. of reach of the devices 41 and 65, and hence the number wheels will retain their normal positions as at Fig. 18, disengaged from their driving racks during the forward stroke of the general operator effected by the handle 31.

Each cam also has a portion 152 which alwa s holds the member 63EL at'the extreme rig t-hand or subtracting position, as shown by the major register 132 in Fig. 5. At said figure thesubtraction key 153 of the lefthand register 133 is shown in its normal.

position, so that said register 133 performs addition while register 132 is performing subtraction, and while register 143 is silenced or neutral. Y

Any of the subtraction shift bars 62, 149

and 153 may be in either of its addition, lsubtraction and neutralpositions while each ofthe other two bars is in either of its three positions." Hence any one of the three registers may either add, subtract, or remain neutral while either one or both of the I remaining registers either adds,. subtracts, or is silenced. If all of the barsv are shifted to the same position as bar 149 in Fig. 5,' all three registers will be silenced or remain neutral, so that they will not disturbed during the operation of the general operator 431; or all may be made to add or all to subtract.- 1

Referring tov Fig. 16, additional dogs 126-127 may be rovided on the typewriter iiese dogs may be adjusted alon the rack 182 forming part of the usual tabu ating mechanism illustrated at Fig. 3. These dogs may be so adjusted thatl each the corresponding ,number in the column,

inions 146 on extensions 147 of so thattwo columns may be written on the age, and the corresponding numbers may e carried into. the registers.

In now describin the details of operation of the bar 62 whic controls the condition of the actuating means for the register 132,

so that the latter is caused either to'add or `to subtract or to remain neutral according to the position of said bar 62, it will be understood that the description applies as well to the other condition-controlllng bars, namely 149 and 153, every register having its own condition-controllmg or shift bar. And while only three registers and three shift bars are shown, it will be understood that the improvements are also applicable to machines having more than three registers.

The condition-controlling or shift bar 62 is shown at Fig. '3 in normal addition position, this being the rearmost of the three positions which said shift bar may occupy. The shift bar is normally held in its extreme rear position by the vgeneral operator.. The spring 62", however, tends to move said bar forwardly to its subtraction position, which is seen at Fig. 17. A latch 158 is interposed for normally preventing said spring 62b from moving said shift bar out of addition position at the forward movement of the general operator. While said spring is suficiently powerful to move the shift bar to operate t e cam member 63, still the force required to withdraw the latch y158 (while the shift bar is being held back by the gen eral operator) is very slight, and hence the 17a, the latter connected by a strap 160 to the carriage.

In order to enable the carriage to control the latch, the latter is pivoted at 161 u on an arm 162, which forms an extension o an arm 163 on a bail, said bail hinged at 164 upon a rock shaft 174 mounted upon the framework of the typewriter. The o posite arms 163 of the bail are connected y a cam member 165, which is shown at Fig. 17.

.This cam member may be depressed by a tap et 166," formed on the denomination selecting member 127, (Which is adjustable along the carriage rack 182). This device 127' may be a'flat blade, having a fork to engage the-rack 182, and having a dog 126 to engage or select the denomination ]acks or levers 124, and also having an extension 166 for operating the cam 1.65. The latter isseen at Fig. 16 as having a cam edge 167 which is being engaged by one of the tappets 171, whereby during the advance move- Lama the latch `158 and withdrawing it from the shoulder 159, with which it is normally 1n engagement, and by which it normally -restrains the shift bar 62 from swinging for Ward. ,'The position of the parts this .time is seen at Fig. 17; the latch 158 having been withdrawn and the spring 62b having the shift bar 62 forwardly a full stroke, thus forcing the portion 152 of the cam member 63 to effectl the shifting of the sleeve 63a to subtracting position, as seen at Fig. 17, and also at the middle portion of Fig. 5.

termined that theregister 132 shall subtract at the movement of the general operator. It will be understood that the displacement of the cam 165 may also be effected by a re turn movementl of the carriage, so vthat whenever the carriage is 1n the computing zone, it determines the position to be occupied bythe shift bar..

Y -the next computing operation.

bar or condition-controlling member 62 may4 fected by the tappet 166, Fig. 18, Awhich does not project down so much asthe tap- 'Upon the return movement of the general operator,A its cross bar 29 engages a lug 168 on this shift bar 62, and drives the same back against the tension of spring 62", and restores the same to its normal extreme rear position; the latch 1-58 bein returned by a spring 169 to a position orward of the shoulder or catch 159 on the shift bar.; so as to be ready to restrain the shiftbar 62 upon the next operation of the general operator, in case subtraction is not to be per.

formed upon the associated register 1 32 at The shift therefore-be normally in addition position,

but may be easily released by the carriage to be power-driven to subtraction position.

The cam 165 is of suiicient length to hold the latch 158 elevated as at Fig. 17, during the entire time that the paper carriage 7 is in this particular computing zone, so that if the general operator handle 31 is actuated at any time while the carriage is in or bordering upon this zone, the register in question will perform subtraction.

The shift or condition-controlling bar 62 is also provided with a shoulder 170, which'. may be brought into requisition for holding l the shift bar 62 in its midway position, to silence the associated register at the actuation of the general operator. For this v'purpose the latch 158 is not entirely withdrawn from the shift bar 62, but is lifted to. a medium position, as at Fig. 18, to'intereept the shift bar 62 at the time that it is in the position seen at the lower portionof Fig. 5, with the sleeve 63a shifted to a midway idle positionm i This'short stroke of the latch 158 is efpet 171, so that the cam bar 165 is only a little depressed, and hence the latch 158 is permitted to intercept the shoulder 170.

I'SLWII Hence, r .a movement .of the paper carriage 7 has de- Each of the othertwo registers is .also

controlled bythe carriage in like manner.

The shift bar 153 has a latch 172, pendent from an 'arm 173, which is fixed on the rock lshaft 174, towhich is secured a bail 175,

having acam 176 forward of the cam 165;

and the shift bar 149 has a latch 177, pend# ent from an arm 178 that projects forwardly from theA bail 179, the latter having la cam 180 forward of cam 176. These cam .bails may be nested, as seen in the plan at Fig. 21, and may be mounted concentrically upon the shaft 174, and ymay also havel at their other ends acommon bearing on a shoulder screw 181; all the bails being vloose on'shaft 174 except bail 175, which is fixed thereto. The two shift bars just mentioned have `the same construction and operation as shiftr bar 62; and the'same is true of the latches, which are similar in construction and operation to latch 158.

At Fig. 21, it will be seen that by having the cams 165, 176 .and180 placed closely one use a single tappet for controlling all three cams Said tappet mayhave any of the forms seen at Fig. 19 The firstdevice seen at said figure, is merely a column stop or column` selector. The one below that is not only a combined columnselector and denomination Selector, but also controls the three cams 165, 17 6 and180 allowing them all to remain in normal position when the carriage is in the adding zone, by. not withdrawing any of the latches 158, 172 and 177 from theirnormal restraining positions, Fig. 3. Since all three registers will perform adding, when said tappet is used, it is vmarked C( A 7 4 .withdrawing .the latch 158 entirely, whereby subtraction is performed upon the-middle register at the computing operation, while addition is performed upon each of the other registers.

The next. tappet shows a projection .marked N for neutral, this projection being over the second cam, which is marked 176, so thatthe upper register 133 vat Fig. 5 will remain neutral while boththeother registers add at the computing operation.` vThe next tappet is used for having the register 143 -add while the other two registers lbehind another, it becomes practicable to are neutral, and so on throughout the set; all of the tappets being marked to indicate the result to be accomplished by their use.

At Fig. 16, several of the combination column stops, denomination-selectors and condition-determining devices are shown adjusted along the rack 182 -of the carriage, for

' locating the positions of the successive columns on the work sheet, and .also controlling the selection of the denomination )acks 124 -and also determining what each column of ders 185 to operate a pivoted device 186, to

depress a link/187 and swing a lever 188 to lift the rack 9 from engagement with the pinion 10, so that the carriage may be driven along by its spring 17a, as usual 1n tabulating operations.

The condition of each register lmay also be manually controlled by means of a handle, which may be at the front of the machine, Figs. 3, 16, 20, 22 and 23. Normally the handle may hang vertically from a rock shaft 190, a spring detent 191 on the handle engaging a notch 192 formed on the framework.

When the handle 189, which is here shown as applied to register 133 is swung to the right, Fig. 20, an arm 193 on the rear end of the rock shaft 190, shoulders the latch 172 to one side, free of its shift or conditioncontrolling bar 153, so that its spring 62b may. at the ensuing forward movement of. the general operator handle 31, drive it forwardly to the extreme position seen at Fig. 17, so that the register 133 Ashall perform subtraction. But if, .before operating the general operator, the user desires that this register 133 shall remain neutral, he shlfts the handle 189 a little farther to the right, as at Fig. 22, so that a projection 194 on the arm 193 shall obstruct the path of the shoulder 170 on the shift bar 153, so that the latter moves only to midway neutral position. Or if he desires that this register shall add, he moves the handle 189 to the extreme position seen at Fig. 23, to bring a projection 195 .in a position` forward of the shoulder 159 on said switch 153, so that the latter shallnot advance with the general operator, but shall maintain a position seen at the upper part of Fig. 5, and hence addition may be performed on this register.

There are four of the notches 192 in each Set, S0 that the detent 191 may hold the handle 189 in any position to Vwhich the operator shifts it from thenormal ineffective position seen at Fig. 16; and the notches may be marked for addition, neutral and subtraction, as shown. Therefore, if'at any time the operator wishes to discontinue-the control of any of the shifting mechanisms by the carriage, he merely needs to adjust the 'handlel 189 to the desired position, where it will stay during the remainder of the time that the combined typewriting and computing machine is operated. If he should set it lat the neutral position, it would have the effect of permanently silencing the -register throughout the use of the machine. Upon restoring thehandle 'to normal position, a spring 195a returns the latchv I to normal position. p

I t will be seen at'Fig. 16, that permanent handles 196 and 197, similar in construction and operation to handle 189,.are provided for the other two registers 132 and 143; so that the operator can 4silence any one or more registers regardless of the others, and can manually control their condition independently of the typewriter carriage, and

can have such control mechanically maintained throughout the remainder of the operation of the machine. I Each of the latches may swing in a transverse gu'ide'slot 198 in a bracket 199, and the arms 193 may also be guided in these slots. The edge of the slotv supports the latch limited by a pin 200 thereon striking the guide-comb 140.

The claims in this case are limited to features not disclosed in the application of Ogden Minton, Serial No.l 797,714, filed Oc-` tober 28, 1913; the invention of said Minton being prior to mine.
